There may well be a better forum to ask this question so that it is found by those with some experience of this.
If you click this link and type in the name of your cancer type some suitable groups will pop up. Just join the one you feel is most appropriate and select 'Join This Group' then you can start a new discussion and your question will reach those who could help.
There are groups for most primary and secondary cancer types including Living with Incurable cancer. It would help if you mentioned the chemotherapy treatments you are having.
